Patent JP-H02171338-A (JP)
Title: Fail-safe device for constant-speed travel device
Inventor: NAITO YASUO
IPC: B60W30/00
Filed: 1988-12-24
Abstract: PURPOSE:To ensure safety by controlling power supply to an actuator to be cut off in case reset signals are generated due to the output stoppage of watchdog signals and the like. CONSTITUTION:A reset signal generating means 5 compares the integrated value and the specified level of the output signal of a watchdog detecting means 4, and outputs reset signals when the integrated value exceeds the specified level. A NOR gate 6 resets a D flip-flop 7 if reset signals from the reset signal generating means 5 or cancel signals from a cancel signal input means 3 operated by an operator are inputted. Accordingly, a terminal Q is put on an 'L' level, and the coils 13a, 14a of a first and a second solenoid valves and a power source 11 become nonconductive. As it is so controlled that power supply to an actuator is cut off in case the reset signals are generated due to the output stoppage of the watchdog signals, the action of the actuator can be positively stopped, so that a device of high safety can be obtained.

Title: Explosion-proof mobile identification system
Inventor: AKIYAMA KOJI
IPC: G01S7/03
Filed: 1994-12-28
Abstract: PURPOSE: To obtain a mobile identification system which can be used in a dangerous place by employing an explosion-proof interrogator and making a window for radiating radio wave at a part of the explosion-proof case. CONSTITUTION: An explosion-proof metallic case having a radio wave radiation window 32 of tempered glass or plastic is employed as the housing 31 of an interrogator 50 thus realizing an explosion-proof structure. The radio wave radiation window 32 is provided to close a hole made through the explosion- proof housing 31 and a radio wave is radiated from an antenna 1 through the window 32 or received by the antenna 1 from a responder 51 through the window 32. Interrogation wave 101 and response wave 102 are transmitted or received through the window 32. Preferably, a radio wave absorber is fixed to the inner periphery of the window 32.  With such constitution, interference due to reflection of radio wave on the metallic part in the housing 31 can be suppressed and a radiation pattern corresponding to the essential characteristics of antenna is produced thus realizing an excellent transmission.

Title: Wiring board
Inventor: YOMO KUNIHIDE
IPC: H05K1/09
Filed: 1994-12-28
Abstract: PURPOSE: To burn both an insulating base body and a wiring conductor at a time, to protect the insulating base body against cracking, and to microminiaturize a wiring conductor by a method wherein the wiring conductor formed on the surface of the insulating base body and/or inside the base body is formed of a specific % by weight of W and/or Mo and a specific % by weight of Cu. CONSTITUTION: A wiring conductor 2 is formed of 40 to 95% by weight of W and/or Mo and 5 to 60% by weight of Cu, so that the wiring conductor 2 is capable of approximating in thermal expansion coefficient from a room temperature to temperatures of 800 deg.C to a sintered body which is at least one out of mullite, cristobalite, and forsterite in main crystalline phase, whereby a thermal stress caused by a thermal expansion coefficient difference between the wiring conductor 2 and an insulating board 1 is prevented from occurring between the conductor 2 and the board 1 when a wiring board is formed, and the wiring conductor 2 is capable of being firmly fixed to the insulating board 1. The wiring conductor 2 can be lessened in electrical resistance and microminiaturized, so that a wiring board is capable of being lessened in size and enhanced in mounting density.

Title: Check point control system
Inventor: IKEDA HARUMI
IPC: G06F11/28
Filed: 1989-12-18
Abstract: PURPOSE:To execute the test of a transaction processing system actually operated at present without interruption by providing the transaction processing system with a declaring means, a check point processing part related a data file, etc. CONSTITUTION:A declaring means 101, a check point processing part 106 related to the data file, etc., are provided. When experimental execution of a specific transaction processing program is declared by the declaring means 101, the check point processing part 106 related to the data file invalidates the data file update results of the transaction processing program if the transaction processing program related to this declaration is normally punctuated in the period when declaration is effective. A check point processing part 105 related to a message is normally operated independently of declaration to output the output message. Thus, the transaction processing program is experimentally executed without stopping the actual operation.

Abstract: PURPOSE:To realize perfect-printing, multi-printing, or the like with high accuracy by a method wherein an image sensor is disposed so as to abut on a printed member in the vicinity of a printed member discharge port of a stacker containing the printed member subjected to the first printing. CONSTITUTION:A sensor 1 is disposed at the leading end of paper 7 or there abouts so as to abut on the paper 7. The output of the sensor 7 is low level in the presence of the paper, but is high level in the absence of the paper.

Therefore, a processor 6 counts the number of clocks after H.SYNC until the output of the comparator 5 is reversed, whereby the position of the paper in a main-scanning direction is identified. After that, a stacker is moved to a proper position under the control by the processor 6 in accordance with a paper position information, and a perfect- or multi- printing can be performed with accuracy.

Filed: 1990-11-27
Abstract: PURPOSE:To obtain a high gain even at a low frequency by connecting an output circuit differentially receiving an output signal outputted differentially from a feedback type limiter amplifier to a post-stage of the feedback type limiter amplifier. CONSTITUTION:Each of amplifier circuits 11-14 has two input terminals and outputs two output signals proportional to a difference between two input signals inputted to the two input terminals, and feedback resistors 15, 16, 18 are connected between the input terminal of the 1st stage amplifier 11 and the output terminal of the final stage amplifier 14.

Filed: 1993-12-01
Abstract: PURPOSE:To provide a compact XY theta table having no ruggedness by arranging a motor for generating a driving force to move each plate in XY theta directions on the same side surface as that of the XYtheta table. CONSTITUTION:Motors MX, MY and Mtheta are fixed on a base B in a line. When a plate PX is moved in an X direction, the motor MX is driven and the PX plate is moved in the X direction by a straight motion cross roller guide 7c via a ball screw 4c. When the motor MY is rotated, a driving force by the straight adcance movement of a ball screw 4a is transmitted to a plate PY via a spring steel 5a and the plate PY is moved in a Y direction. When the motor Mtheta is rotated, a driving force by the straight advance movement of a ball screw 4b is transmitted to a plate Ptheta via a spring steel 5b and the plate Ptheta is moved in a& direction. Thus, the movements of the ball screws 4a and 4b in X direction are converted to the movement of the PY plate in the Y direction and that of the plate Ptheta in the theta direction by using the spring steels 5a and 5b.
